Abstract

The utility model relates to a world clock system, which is characterized by comprising a control module, a storage module, a display drive module and an input module respectively connected with the control module, wherein, the display drive module is also connected with a display. The world clock system uses a singlechip to make the clock system small and portable for user and can display the time all over the world to simply find out the global time information.

Description

A kind of World clock system

Technical field

The utility model relates to a kind of SCM Based clock system, is specifically related to a kind of World clock system.

Background technology

At present, common clock system generally is based on clock and watch class machinery or electronic equipment, and the shortcoming of this kind clock system is a function singleness.Existing have multi-functional clock system and mostly operate on the electronic equipment such as computing machine, and its shortcoming is, because the limitation of its hardware volume causes the user to be difficult to carry these clock systems.

The utility model content

The utility model provides a kind of World clock system, can show the correct time of all parts of the world, and is easy and simple to handle, easy to carry, practical.

For achieving the above object, the utility model provides a kind of World clock system, and it comprises control module, and the memory module that is connected with control module respectively, driver module and load module, and this driver module also is connected with display.

Above-mentioned control module comprises arithmetical unit and controller.

The utility model is compared with the clock system of prior art, has the following advantages:

The utility model adopts the form of single-chip microcomputer, makes this clock system volume small and exquisite, makes things convenient for the user to carry;

The utility model can show the time in all parts of the world district, can understand the residing time of various places easily.

Description of drawings

Fig. 1 is the general structure synoptic diagram of the utility model World clock system.

Embodiment

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.

See also shown in Figure 1ly, the utility model World clock system comprises control module 1, and the memory module 2 that is connected with control module 1 respectively, driver module 3 and load module 4, and described driver module 3 also is connected with display 5.

Control module 1 and memory module 2 in the utility model, the hardware device of employing is the XSBASE270 development board, the ARMV4I embedded microprocessor that this development board adopts ARM company to produce.The driver of XSBase270 experiment porch is provided by platform BSP, comprising input equipment (Input Devices), the network equipment (Networking), PC card (PC Card), SD card, serial ports, touch-screen, USB device etc.; Also comprise Emdoor OEM driver in addition, it mainly comprises: CAN bus driver, ide interface driving, LED display driver, motor interface driving etc.The software systems that development board XSBASE270 adopts in the utility model are WinCE, because framework is similar substantially with the windows system, so as long as recompilate some codes, just be easy to the software transplanting of some desktop systems in the WinCE system.

In the utility model, the dot matrix graph lcd module DMF5005N that driver module 3 adopts Toshiba Corp to produce, characteristics such as volume is little, in light weight, low-voltage, low-power consumption that it has.DMF5005N comprises control circuit, and the horizontal drive circuit that is connected with control circuit respectively, column drive circuit, electric power bias circuit, display-memory.Control circuit mainly is made up of controller T6963C, provides with the data-interface of outer CPU and to the read-write operation of display-memory, sequential circuit, data layout and the display format of control row, column driving circuit; Horizontal drive circuit is made up of line driver T6A40, and the FR of controller is connect the FR end of T6A40, and VLC1, VLC4, VLC5 are received the corresponding terminal of electric power bias circuit, and what can guarantee driver output is the capable drive level of LCD screen; Column drive circuit is made up of three row driver T6A39, adopts three T6A39 chips to link, and constitutes 240 row outputs; Display-memory is made up of the RAM random access memory of a 8k, can be the storage space that module provides video data.And display screen has adopted the LCD LCDs in the utility model, and the dot matrix display screen curtain of 64 row, 240 row is provided.

After finishing hardware architecture and debugging, the World clock program of writing is written into this clock system, this program mainly is divided into 4 big modules:

First module is: the inquiry in area, can input inquiry or select inquiry, and if exist in the drop-down list box, just can demonstrate time corresponding.

Second largest module is: show the result who is inquired about, refresh demonstration in real time with numeral and picture dial plate.

The third-largest module is: the keeper lands the time zone query interface, and keeper's username and password all is: " admin ".

The fourth-largest module is: after landing the time zone query interface, can carry out the interpolation in time zone, and inquiry, functions such as preservation are removed in deletion.

In the utility model, load module 4 adopts touch-screens, uses zebra time during function, imports the location in choice box, selects the area that will search again with in the combobox, operates to show the local time.And, can in this World clock system, arbitrarily add required area and time-zone information thereof on demand, independently enrich systemic-function.

Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be conspicuous.Therefore, protection domain of the present utility model should be limited to the appended claims.

Claims
